I finally decided to build a skid steer type design, I've spend months hanging out in a scaled tank site and got the idea of how to build a belt driven transmission that will run a small skid steer vehicle, not for real work but - to just be building it. lol I bought a mig gaseless welder, & I ordered lotts of parts, a 6.5 engine. pulleys. sprockets, chain & Tires, pillow block bearings, axles..and angle iron ectt..and drill bits, lol so here i go. I'm taking pics and will upload them .
